SkimFast

About

SkimFast opens any X (Twitter) post's full reply thread in a popover, right over your feed. One click — read the whole conversation, then keep scrolling. No new tab, no clicking into the post and back out.

What you get:
• Full reply threads in a popover, in one click
• Real nested reply chains, grouped the way X shows them
• Sort replies — Default, Top (most liked), or Latest
• Jump to the top of the thread, or to the most-liked reply
• Drill into any reply's own sub-thread, with a back button
• Images and video play right inside the popover
• Hover the Skim button to preview the top replies before you open
• Matches your X theme automatically — light, dim, or lights-out, down to the Chirp font
• A keyboard shortcut to skim the post centered on your screen

Private by design:
• Runs entirely in your browser. No SkimFast servers, no analytics, no tracking.
• Works on your own logged-in X session — it only shows threads you could already see.
• The only thing it ever sends out is your license key, to verify your purchase.

Pricing:
One-time payment, lifetime license. Every feature and all future updates included. Works on up to 3 devices — move a device anytime.
